Default Looking for experience/documentation RS-232 port on Harmon-Kardon A/V receivers

Hi there -

I've noticed that some Harmon-Kardon receivers (AVR-430, etc) sport an
RS-232 port. According to the brochure, "This jack may be used to control
the AVR-430 over a bidirection RS-232 serial control link".

Does anyone in these groups have any experience with this, or have a pointer
to the documentation for the command set, etc?

Thanks much in advance!

My experience has been that most monufacturers advertise the RS-232 ports as
a "feature" to help sales, then klutch the protocol to their bosom and
refuse to let anyone (other than high-end home automation vendors with lots
of cash for license fees and lawyers for non-disclosure agreements) know
what it is.

I have a B&K receiver mainly because B&K was willing (if only through a
very informal channel) to release their protocol info.
